My 12 8 week old chicks have been outside in their coop and run for almost 2 weeks. we took the heat lamp away a few nights ago since they are fully feathered. The temps are in the low 40s for night time and yesterday it started to rain and its suppose to last another day or 2. I have been letting them out to the run in the morn for an all rainy outting and they put themselves to bed at about 730 then I close them up for the night. Is this ok or because I just took the heat lamp away is adding rainy weather to the list of new things too soon? Also we are going to have a few night coming up soon that will be in the 30s they should be ok right? I figured turning the light on some nights and off others may confuse them or wreck the progress weve made to get them off the heat? Any comments suggestions or advice?.
